The SPNS (Step Seal with PTFE and O-Ring Energizer) is a static hydraulic rod seal installed in gland housings to prevent fluid leakage during rod reciprocation. Its design includes: PTFE Slip Ring: Provides ultra-low friction, chemical resistance, and thermal stability. Elastomeric Expansion Ring (O-Ring): Compensates for PTFE’s rigidity by supplying elasticity and initial sealing force. Bronze-F...
A gate valve rubber polypak seal is a crucial sealing component in gate valves. It is designed to provide effective sealing to prevent fluid leakage. Here is a detailed introduction: Material Material: High - quality rubber materials are commonly used, such as nitrile rubber, fluororubber, and silicone rubber. These rubber materials have excellent sealing performance, wear resistance, and corrosio...
In the demanding world of oilfield downhole operations, reliability under pressure is paramount. The V-Stack seal assembly emerges as a critical component in valves, fracturing systems, and other high-stakes equipment. Engineered to excel in medium to heavy-duty applications, Chevron Vee Packings deliver unmatched performance in extreme temperatures, pressures, and even misaligned sealing gaps. Du...
In the oil and gas industry, ensuring well integrity under extreme pressures and abrasive conditions is non-negotiable. The P Seal for casing and tubing stands out as a cutting-edge static sealing solution engineered to address the challenges of sealing rough surfaces while delivering redundant safety in critical wellhead applications. Constructed from a high-performance elastomer, the P Seal inte...
The NORSOK M-710 RGD test is a standard for the performance of rubber sealing materials under rapid gas decompression (RGD) conditions. The test is designed to evaluate the ability of sealing materials to withstand pressure and rapid gas decompression in the oil and gas industry. The test standards and methods The NORSOK M-710 standard specifies the specific conditions and steps of the test: Test...
In Liquefied Natural Gas (LNG) operations, valves and equipment face some of the harshest conditions on Earth: temperatures plunging below -320°F (-196°C), pressures exceeding 750 psi, and constant thermal cycling that causes hardware expansion, shrinkage, and material stress. These challenges demand seals that can maintain integrity over the long term while ensuring safe, leak-free operation. Eff...
When it comes to sealing solutions in extreme environments, FFKM O-rings stand out as a top choice for industries demanding uncompromising performance. FFKM, or Perfluoroelastomer, is a high-performance material known for its exceptional chemical resistance, thermal stability, and durability. What Are FFKM O-Rings? FFKM O-rings are sealing components made from Perfluoroelastomer, a synthetic rubbe...
Valve stem packing seals are used in valves to provide a seal around the valve stem (the shaft that controls the valve's opening and closing). They are essential for preventing fluid or gas leakage from the valve, ensuring that pressure and contaminants don't escape. The application of stem packing seals includes: Pressure Control: They help maintain pressure within the valve, preventing leakage a...
Reducing fugitive emissions has become a high-priority goal for nearly all processing plants and facilities around the world. Often, the valve technology itself has a significant impact on fugitive emissions and therefore the life cycle cost of the equipment. According to the research, one of the largest sources of fugitive emissions in plants is associ ated with valves. The bulk of valve emission...
